This is one nice little game. The vector graphic is certainly very cute, and the music is pretty soothing. Gameplay wise I really like it too
Innovation wise this is pretty lacking though... I think there are dozens of games of this genre that I have played before... and this seems to only very barely fit the theme (is this supposed to follow 'bound' as in the arena is just that small bounded area?). Also there is a spelling error ("Your jurney ends here" - is this intentional to make the game seem childish? Doesn't seem intentional to me; if it's not you should fix it)
Anyway this is pretty good. Great job!
